Title: Manufacture of wave absorber
Inventor: TSURUTA MAKOTO
IPC: H05K9/00
Filed: 1988-12-27
Abstract: PURPOSE:To manufacture speedily and at a low cost by forming a wave absorber in which a core made of high-strength resin and a cover made of a soft material like a foaming material or rubber are integrally formed. CONSTITUTION:A wave absorber 1 is of a regular quadrangular shape, i.e., a pyramid. This wave absorber 1 is structured from two layers of a core 21 and a cover 3. The core 2 is formed by polypropylene resin, the inside of which is hollow. The cover 3 covering the outer surface of this core 2 is formed by a soft material like a foaming material of foaming urethane or rubber. Carbon powders are added, as a wave absorber, to resin forming the core 2. Thus, the core 2 has the property of conducting electricity and wave absorbing characteristics. By adding carbon powders to the cover 3 without making the core 2 have wave absorbing characteristics, this may have the wave absorbing characteristics. The electric conduction value can be set any value by the amount of addition by adjusting the amount of carbon.

Title: Packing for sealing relatively displayed junction plane and junction plane sealing structure by using the packing
Inventor: YOKOZUKA YUKIFUMI
IPC: F16J15/46
Filed: 1991-11-19
Abstract: PURPOSE:To provide a packing which is hardly twisted when a junction plane is displaced and a junction plane sealing structure which helps extend the service life of the packing. CONSTITUTION:To seal a relatively displaced fixed table 4 to the junction plane of a vacuum frame 7, a packing 11 is provided in between the outer periphery 4a of the fixed table and time inner periphery 7a of the vacuum frame 7. The packing 11 is formed so as to project a rib 14 to one major-axial end in sectionally elliptical shape. The packing 11 is fitted to a groove strip 10 provided in the outer periphery 4a so as to be displaced by fluid pressure into contact with or separate from the inner periphery 7a. The packing 11 is hardly twisted in the groove strip 10 because of the operation of its sectional shape. A junction plane sealing structure helps prevent the wear of the packing 11 during displacement and extend its service life because the packing 11 is separated from the junction plane when the junction plane is relatively displaced.

Title: Signal generating circuit for down-sampling
Inventor: KOBAYASHI NAOKI
IPC: H04N11/16
Filed: 1997-12-01
Abstract: PROBLEM TO BE SOLVED: To obtain a stable down-sampling signal from a video signal of the phase alternation line PAL system without the use of a complicated PLL. SOLUTION: A 4-multiple subcarrier signal 103 obtained by multiplying a subcarrier signal included in a video signal 101 by a multiple of 4 is frequency- divided at a frequency division ratio of 1/1136 for a head and a middle of one field and at a frequency division ratio of 1/1135 for other parts in a horizontal blanking period, and a down sampling signal 106 is generated by using the frequency division signal. Thus, a deviation in 0.0064 sample per line in the video signal 101 of the PAL system is corrected with a simple PLL configuration from the video signal 101 of the PAL system and the stable down sampling signal 106 is obtained.

Title: Vacuum carburization method
Inventor: MURAOKA TOMOKI
IPC: C23C8/20
Filed: 1992-12-10
Abstract: PURPOSE:To prevent the generation of soot by cracking of gaseous hydrocarbon in a carburization furnace, by specifying the mixing ratio of the gaseous hydrocarbon and air in an atmosphere for carburization at the time of subjecting the surface of a metallic member to a carburization treatment in the vacuum carburization furnace. CONSTITUTION:The metallic material W to be subjected to the carburization treatment is put into a vacuum heating furnace 11 of a vacuum carburization device. After this heating furnace 11 is internally evacuated to a reduced pressure by a vacuum pump 62, the metallic material W is heated up and gaseous propane and air are supplied into the heating furnace 11 by opening a solenoid valve 33 of a gaseous propane cylinder 30B and a solenoid valve 32 of an air cylinder 30A. The gaseous atmosphere mixture in the heating furnace 11 is sampled from a suction pipe 52 and is subjected to the measurement of the oxygen partial pressure in the gaseous atmosphere by an oxygen partial pressure gage 40. The air and the propane are supplied by the solenoid valves 34, 35 from cylinders 31A, 31B for control so that the ratio of the propane and air in the gaseous atmosphere attains 1:3 to 1:5. The C generated by cracking of the propane in the gaseous atmosphere for carburization is oxidized to CO with the O2 in the air and, therefore, the generation of the soot in the heating furnace 11 is prevented.

Title: Apparatus for judging dry state of surface of concrete aggregate
Inventor: NAKAJIMA KIYOSHI
IPC: G01N5/04
Filed: 1988-12-27
Abstract: PURPOSE:To facilitate the judgment of the changing point of a drying speed by forming the linking parts of the bottom part and the side surface part of a container for accommodating aggregate in an R shape, and blowing drying hot air into the container along agitating members. CONSTITUTION:A container 8 has a semispherical shape. The bottom surface and the side surface are linked at an R part. The container is turned so that edges are not formed. Agitating rods 20 are provided along hot air jetting ports 18 for jetting the hot air from a constant temperature oven 6. Thus the sticking of the wet aggregate to the agitating rods 20 is prevented. The lower part of the aggregate which has risen up along the wall of the container 8 is collapsed with the agitating rods 20, and the aggregate is made to fall down. Then the weight of the aggregate is measured with a scale 32. The amount of free water contained in the aggregate is obtained based on the different between the initial weight and the weight in the dry state of the surface. In this way, the changing point of the drying speed of the aggregate can be judged readily.
